Not only does politics and general stories crowd out everything else over time on other sites, there are HN submitters who seem to be trying to accelerate this.

During the war, when HN was getting Israel-Palestine stories constantly, I started looking at the submission history of some of the submitters, and some of them were just pushing these types of stories every day for months and months.

So yes, I think allowing politics will eventually mean being dominated by politics and general interest.
